    摘要： This invention provides a negative electrode active material for lithium ion capacitor, which reduces the thickness of a negative-electrode active material layer while maintaining the conventional level of energy density.
    The negative-electrode active material for a lithium ion capacitor is a composite carbon material manufactured by kneading a carbon black having an average particle diameter of 12 to 300 nm measured by the electron microscopy method with a carbon precursor such as pitch, the resulting mixture is baked or graphitized baking between 800°C to 3200°C, and then pulverized such that the average particle diameter (D 50 ) thereof is 1 to 20 µm and the BET specific surface area is between 100- 350 m 2 /g. An initial charging capacity is at least 700 mAh/g, and the cell volume is reduced as the thickness of the negative electrode active material layer becomes thinner than the conventional one.
